STREET-STANCHION.

To all whom it may concern:

Be it known that I, HERMAN AUBERLIN, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inStreet-Stanchions, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to a trafiic sign, and more particularly to astreet stanchion or post employed for indicating safety zones, reservedor restricted territory, and lanes of travel.

The objects of my invention are to provide a traflic sign that can becountersunk in the street and easily and quickly raised to an operativeposition, and to provide novel means for safely housing such a sign whennot in use.

Other objects of my invention are to provide a street stanchion or postthat can be made a street fixture, thereby obviating the necessity oftraflic oflicers moving stanchions or posts from one position toanother, and to furnish street stanchions or posts of the above typewith detachable signs that permit of the stanchions or posts being usedfor various purposes.

With the above and other objects in view the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed, and reference willnow be had to the drawings, wherein- Figure 1 is a longitudinalsectional view of a portion of a tubularcasing constituting a combined'support and housing for a stanchion; Fig. 2 is a view in elevation andpartly in section of a traflic stanchion; Fig. 3 is a plan-or view ofthe upper end of the street casing, and Fig. 4 is a diagrammatic view ofa portion of a street provided with traflic stanchions in accordancewith my invention.

In the drawing, the reference numeral 1 denotes the tubular casing orhousing that has one end thereof open and the opposite end closed, withthe exception of a small drain opening 2. An inner wall of the easinghas a longitudinal groove 5 for the greater part of its length and theupper end of the groove communicates with a semicircular groove 6, saidgroove 6 communicating with the lower or inner end of a Specification ofLetters Patent.

Application filed October 12, 1914. Serial No. 866,210.

longitudinal groove 7 extending to the open end of the casing Thegrooves 5, 6 and 7 provide clearance for a pin 8 projecting laterallyfrom a tubular stanchion or post 9 slidable in the casing 1 and adaptedto be housed thereby. The pin 8 is in proximity to the lower end of thestanchion or post and when in the groove 6 supports the stanchion in anelevated position, as shown in Fig. 2. By rotating the stanchion aquarter of a revolution in one direction the pin 8 alines with thegroove 5 and permits of the stanchion being lowered. While rotating thestanchion a quarter of a revolution in' the opposite direction the pin 8alines with the groove 7, whereby the stanchion can be completelyremoved. This is essential in order that the stanchion can be painted orrepaired.

The upper end of the stanchion 9 is provided with a detachable plug 10having a central opening 11 with the walls thereof screwthreaded toreceive the threaded stem 12 of a sign holder 13. The sign holder isprovided with a suitable sign 14 upon which can be painted or otherwisemarked Safety zone or other appropriate directions or indications.

A cap 19 having a depending flan 'e 4 is made part of the pluglO anddetacha ly retained upon the upper end of the stanchion by said plug.The cap 19 is adapted to enter a sleeve 20 countersunk in the paving 3.The sleeve 20 has inwardly projecting lugs 21 adapted to rest upon aperipheral collar 22 of the casing 1, and said sleeve cooperates withthe upper end of the casing 1 in providing an annular compartment toreceive thedepending flange 4 of the cap 19, whereby the cap may lieflush with the paving 3.

Sign holders can be easily attached'and detached relative to the plug 10and positioned to display the sign in a desired direction. Sign holdersalso serve functionally as handles or hand grips for raising andlowering the stanchion, also as means for retaining chains or otherflexible connections 27 between a series of the stanchions arranged todefine safety zones or lanes 0 travel, as shown in Fig. 4.

In some cities, stanchions are in use that have heavy base pieces and inorder to provide or eliminate a safety zone or lane of travel it isnecessary to wheel or carry the stanchions from one position to another,

such operation being laborious on account of the unwieldy nature ofthe'stanchion. F urthermore, When a safety zone is to be eliminated onaccount of fire it is impossible for a single traflic officer to quicklymove a series of stanchions and provide clearance for fire apparatus.With my'improved stanchions,

such labor and trouble is eliminated, as a traflic oflicer can easilyand quickly place the stanchions'out of commission and just as readilyestablish a safety zone when occasion requires. Should a stanchion bebent, bro-ken thereof below the surface of the pavement, a

collar carried by the upper end of said casing, a sleeve having inwardlyprojecting lugs supported by said collar around the upper end of saidcasing and said sleeve projecting above the casing and adapted to becountersunk in the pavement to cooperate with the upper end of saidcasing and providing an annular compartment, said sleeve having bothends thereof open, a. post in said casing adapted to be raised andlowered relative to and removed therefrom, means adapted to hold saidpost in raised position, a cap carried by the upper end of said post andhaving a depending flange, said cap with its flange adapted to lie flushwith the pavement above the top of said casing in the compartment formedby said sleeve and the upper end of said casing.

In testimony whereof I aflix my signature in presence of two Witnesses.
